While Luke Bryan might have been feeling a bit under the weather during his tour stops in Southern California, but that didn't stop him from pranking one of his tour mates.

In a recent interview with ABC News Radio, Lynch tells them the story behind his shirtless photo.

On the road for the Kick The Dust Up Tour, Luke Bryan and tour mate Dustin Lynch made a two-day stop in Irvine, California where it was sunny and 75 degrees. Not thinking anything of it, Lynch decides he's gonna pull up a chair and get his suntan on.

“And so I’m minding my own business in front of my bus and what I didn’t know was there was a trailer or something that was super shined up, so he could see my reflection in the back of this trailer. He was on the other side of his bus cooking soup.” Lynch recalls.

Luke couldn't help but to take advantage of the opportunity to poke fun at his co-star. Taking a jab before Lynch even knew what was happening, Luke snapped a pic of his friend's sunbathing setup and shared it with the world.

“I’m just laying out getting my suntan on, taking a little nap and I hear something to the left,” Dustin says. “Then I hear right behind me, so I jerk around and [Luke]’s filming me. And then he goes, ‘Hey I just tweeted a picture of you’ and I’m going, ‘God that’s the last thing we need out there you know is an unapproved shirtless picture!’” he laughs.

Celebrating the recent success of his No. 1 hit, the country cowboy didn't seem to have much worry about the candid pic, but he did vow that he'd get even.

"He loves picking on me. He does it every night onstage. And there will be retaliation. Stay tuned. Stay tuned,” he laughs.

Following the last few concert dates of the Kick The Dust Up tour, Lynch is heading out on his 2016 Kill The Lights tour after a short break.
